Water Water covers 71% of the Earth's surface; the oceans contain 96.5% of the Earth's water. The Antarctic ice sheet, which contains 61% of all fresh water on Earth, is visible at the bottom. Condensed atmospheric water can be seen as clouds, contributing to the Earth's albedo.

What percent of Earth is water? To break the numbers down, 96.5% of all the Earth's water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact.

How Much of the Earthâs Water Is Drinkable? It is interesting and quite shocking to note that less than 1% of the water on earth is drinkable. Freshwater. This may come as a surprise for many because water makes up seventy-percent of the Earth’s surface. However, despite the fact that three-fourths of the Earth is made up of water, only 2.5% of this is freshwater, while the rest is in the form of sea water, and is therefore not suitable for drinking.

Introduction Oceans, which are the largest source of surface water, comprise approximately 97 percent of the Earth's surface water. However, since the oceans have high salinity, the water is not useful as drinking water. Efforts have been made to remove the salt from the water (desalination), but this is a very costly endeavor.

Amount of fresh water on earth? The ocean holds 97 percent of the Earth's water; the remaining three percent is freshwater found in glaciers and ice, below the ground, or in rivers and lakes. Of the world's total water supply of about 326 million cubic miles of water, over 96 percent is saline, found in the ocean. Written Aug 26. • Asked to answer by.

- Water covers 71% of the Earth's surface; the oceans contain 96.5% of the Earth's water. The Antarctic ice sheet, which contains 61% of all fresh water on Earth, is visible at the bottom.Condensed atmospheric water can be seen as clouds, contributing to the Earth's albedo.arth's approximate water volume (the total water supply of the world) is 1,338,000,000 km 3 (321,000,000 mi 3). Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle.

Distribution of water Distribution of water. The world's oceans contain 97% of the water in the hydrosphere, most of which is salt water. Ice caps, like that found covering Antarctica, and glaciers that occupy high alpine locations, compose a little more than 2% of all water found on earth.

How much water is there on, in, and above the Earth? The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. Water is never sitting still.

Universe Today Space and astronomy news Earth’s Surface Features: Unlike other planet’s in our Solar System, the majority of Earth’s surface is covered in liquid water. In fact, about 70.8% of the surface – which works out to 361.132 million km² (139.43 million sq mi) – is covered by water, with much of the continental shelf below sea level.

Earth About 71% of Earth's surface is covered with water, mostly by its oceans. The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack.

- Sometimes, all three states are even present in the same time and place, such as this wintertime eruption of a geyser in Yellowstone National Park. In all, the Earth’s water content is about 1.39 billion cubic kilometers (331 million cubic miles), with the bulk of it, about 96.5%, being in the global oceans.

What percent of Earth is water? If you were to gather all the Earth's fresh water together as a single mass (as shown in the image above) it is estimated that it would measure some 1,386 million cubic kilometers (km3) in volume. Illustration showing all of Earth’s water, liquid fresh water, and water in lakes and rivers. Meanwhile, the amount of water that exists as groundwater, rivers, lakes, and streams would constitute just over 10.6 million km3, which works out to a little over 0.7%.

How Much Water Is on Earth? If Earth was the size of a basketball, all of its water would fit into a ping pong ball. How much water is that? It's roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey. Some 72 percent of Earth is covered in water, but 97 percent of that is salty ocean water and not suitable for drinking. There's not a lot of water on Earth at all, said David Gallo, an oceanographer at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts.

Water cycle The storehouses for the vast majority of all water on Earth are the oceans. It is estimated that of the 332,500,000 mi 3 (1,386,000,000 km 3) of the world's water supply, about 321,000,000 mi 3 (1,338,000,000 km 3) is stored in oceans, or about 97%.s the Earth's surface water evaporates, winds move water in the air from the sea to the land, increasing the amount of fresh water on land. Play media. Water vapor is converted to clouds that bring fresh water to land in the form of rain or snow.

- Water is the most abundant chemical compound present on Earth's surface. About 2.1% of all of Earth's water is frozen in glaciers. If we use the analogy that 1,000 drops of water represent all of the water on Planet Earth, then we learn that: 1  972 drops are in the oceans and inland seas (97.2%)  21 drops are in glaciers (2.1%)

- EARTH'S OCEANS Oceans cover about 70% of the Earth's surface. The oceans contain roughly 97% of the Earth's water supply. The oceans of Earth are unique in our Solar System. No other planet in our Solar System has liquid water (although recent finds on Mars indicate that Mars may have had some liquid water in the recent past).

The World's Water Distribution of Earth's Water. In the first bar, notice how only 2.5% of Earth's water is freshwater - the amount needed for life to survive. The middle bar shows the breakdown of freshwater. Almost all of it is locked up in ice and in the ground. Only a little more than 1.2% of all freshwater is surface water, which serves most of life's needs.

What percentage of water is freshwater? Confidence votes 177. The total volume of water on Earth is about 1.4 billion cubic kilometers, around 41 million of which is fresh water. 3 percent of the world's water is fresh, however only 0.768% is usable for consumption. The remaining portion of fresh water is locked up in glaciers, permanent snow fields, the Arctic, Antarctica, the atmosphere, living organisms (plants and animals) or is polluted.
